| [Abstract] Objective To explore the application value of MR fluid-attenuated inversion recovery (FLAIR) sequence in the diagnosis of ischemic stroke. Materials andMethods The clinical and MR imaging data of 150 patients with ischemic stroke treated in the hospital between January 2019 and March 2020 were retrospectively analyzed. According to the strength of FLAIR sequence hyperintense vessel sign (HVS), the patients were divided into group A (HVS＜5 points, n=53) and group B (HVS≥5 points, n=97). Clinical and imaging characteristics of the two groups were compared. The relationship between different HVS scores and the severity of neurological deficit and cerebral collateral circulation compensation grading, the relationship between Alberta Stroke Program Early CT Score (ASPECTS) on diffusion weighted imaging (DWI-ASPECTS) and cerebral infarction volume were analyzed.Results There were no significant differences in gender, age, time from onset to MR examination, hypertension, diabetes, hyperlipidemia, smoking history and drinking history between the two groups (P＞0.05). The proportion of atrial fibrillation and National Institute of Health Stroke Scale (NIHSS) score of group A were higher than those of group B [39.62% vs. 20.62%, (14.65±2.54) points vs. (12.87±3.27) points] (P＜0.05). The grade of cerebral collateral circulation compensation and DWI-ASPECTS score were lower than group B [(1.86±0.45) vs. (2.27±0.64), (7.76±1.23) points vs. (8.25±1.34) points] (P＜0.05). The cerebral infarction volume of group A was larger than that of group B [(54.28±12.34) cm3 vs. (25.67±8.63) cm3] (P＜0.05).Conclusions MR FLAIR is of value in the diagnosis of ischemic stroke. The higher the HVS score, the better the cerebral collateral circulation compensation, the milder the neurological deficit, and the smaller the cerebral infarction volume, which is of great significance for ischemic stroke. |
